Siemens 6SL3246-0BA22-1FA0 SINAMICS G120 CU250S-2 PN Control Unit 24V DC PROFINET

The Siemens 6SL3246-0BA22-1FA0 is a high-performance control unit for SINAMICS G120 modular drive systems， providing advanced vector control with encoder feedback for single-axis applications， basic positioning (EPOS) via optional license， and integrated PROFINET communication with IRT support for real-time industrial networks.

Applications

• Position and speed control for conveyor systems, packaging lines, cranes, hoists, gantries， and printing machinery

• High-performance applications with a large number of I/O and demanding speed/torque control (pumps, fans, compressors, mills, mixers, extruders)

• Safety‑related motor control (emergency stop, torque off) with integrated STO, SBC, and SS1

• Upgrade and retrofit of existing G120 drive systems for positioning or closed‑loop speed control

Key Features

• PROFINET IRT interface with two‑port switch for real‑time (RT) and isochronous real‑time (IRT) communication， 10/100 Mbit/s， supports PROFIdrive profile via PROFINET, EtherNet/IP

• Universal vector control modes – V/f (VxF), sensorless vector (SLVC), full closed‑loop vector (FVC) with encoder feedback for high dynamic performance

• Built‑in basic positioner (EPOS) – activate via optional “Extended Functions” license for positioning tasks (license codes: e.g. 6SL3054-4AG00-2AA0‑Z E01 for CU250S-2)

• Integrated Safety Integrated functions as standard: Safe Torque Off (STO)， Safe Brake Control (SBC) (terminal or PROFIsafe)， Safe Stop 1 (SS1)〔7#L33-L36】,【8#L6-L7】. Additional functions (SLS, SSM, SDI) via “Extended Safety” license〔7#L36-L38】.

• Flexible encoder interfaces – D‑CLiQ for direct connection to Siemens encoders； HTL/TTL/SSI via a 15‑pin Sub‑D connector， resolver/HTL via terminals〔4#L16-L17】【7#L15-L16】. Two encoders can be connected simultaneously〔7#L23-L25】.

• Comprehensive I/O and connectivity – Up to 15 digital inputs (4 configurable as I/O)， 3 fail‑safe inputs， 3 relay outputs (1 fail‑safe)， 2 analog inputs (±10V/0‑20 mA)， 2 analog outputs (0‑20 mA)； USB and SD/MMC slots for parameter backup〔5#L17-L18〕.

• Compatible with PM240‑2 (0.55‑132 kW) and PM240 (up to 250 kW) power modules〔7#L39-L40〕; dimension: 73 mm (W) × 199 mm (H) × 67 mm (D)， weight 0.61 kg， IP20〔15#L12】.
